JAMES A. HENRY AND 'oFFlcE.

. FORMING MACHINE.

Application filed January 9, 1922. Serial No. 528,107.

To all whom it may concern:

Be it known that we, JAMES A. HENRY and THADDEUS S. WVAIT, citizens of the United States, residing at Sturgis, county of St. Joseph, State of Michi an, have invented certain new and use 111 Improve ments in Forming Machines, of which the followingis a specification. r

This invention relates'to improvements in forming machines. r We have especially designed our improvements for the forming of curtain rods and 1n the accompanying drawing we have .il-'

lustrated the same as adapted for thatrpurpose. Our improvements are, however, readily adapted to the forming of other and heavier channel-shaped articles.

The main objects of the invention are: First, to provide an improved machine for the forming of curtain rods which is of pro-. duces a superior product in that 1t is very large capacity and at the same time uniform.

Second, to provide an improved machine of the class described which may beadjusted to compensate forvariations in the ga e of the metal worked upon.

Further objects,'and objects relating to structural details, will definitely appear from the detailed. description to follow.

e accomplish the objects of our invention. by the devices and means described in the following specification. The invention is clearly defined and pointed out-in the claims.

A structure which is a preferred embodiment of our invention is'clearly illustrated in the accompanying drawing, forming a part of this application, in which:

Fig. I is a plan view of a bending machine embodying the features of our in.-

vention, as adaptedfor the forming of curtaln rods.

Fig. III is a detail section ona'line correjslponding to'line 3 3 of Figs. III and 'II Fig. IV is a transverse section through 1the feed rolls on aline corresponding to me being shown in in. illustration.

uFig; V is a detail section on a line corresponding to line 5-5 of Fig. I, showing details of the first set of forming rollers.

Fig. VI is a detail section "on a line corresponding to line 6-6 of Fig.- I, showing details or the second set of forming rollers.

Fig. VII is a detail section. on a line corresponding to line 7-[7 of Fig. I, showing details of the third set of forming rollers.

Fig. VIII is a detail section on a line full lines for convenience corresponding to line 88 of Fig. I, showing details of the fourth set of forming rollers.

Fig. IX is a detailxsection on a line corresponding to line 9-9 of Fig.1, showing details of the fifth set of forming rollers.

Fig. X is a perspective view of. a piece of'the finished work.

In the drawing similar reference characters refer to similar. partsthroughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to, the drawing,-'the,base 1 is in the form of a bar extending the length of the machine and provided with shoulders 2' The shafts 6 and 9 are arranged'in' pairs,

the bearing membersS having eccentric portions 10 engaging the bearingv openings 7 so thatby rotating these bearing membe'rs 8 the shafts 9 are shafts 6.

1 To-securethe bearing members 8 in their adjusted positions one of the supporting plates has inverted T-shaped slots 11 disosed between adj acen'tpairs' of bearing openings with their cross or horizontal portions 12 opening into the bearing Openings as 4-4C of Figs. 1, IIandIII, the shafts adjusted towards and from the,

' the roll is of such shown in Fig. II. Screws 13 extend through these slots so'that the partially severed portions ofthe plates may be clamped upon the bearing members, thus retain-ing them in their adjusted positions. At the ends of the plates areslots 14L extending to thebearing openings.

The shafts are connected in pairs by the gears 15 and these pairs of gears are connected by the pinions 16, the center pinion 17 being driven from the shaft 18. With thisarrangement all of the shafts are driven and. at uniformspeeds.

I The feeding and forming rolls are mount-r ed on the pairs of shafts.

\ nelthe work, as shown "in Fig. V, the roll 24 having a channeled; periphery, the ends of which are'disp osed at an obtuse angle to the bottom. ingly entrantsliaped periphery which rolls thework into the channel of the roll 23.v

. acute, thus further The second pair of forming rolls 26,':see Fig. V I, is substantially the same as the first except forming the work.

The third pair of rolls 27' and 28 is shaped to receive the flanges of the'work at right angles, the channel ofthe roll 2'? having its sides at right angles to theaxis of the roll, theenstrant"periphery of the coacting roll being"correspondingly shaped.

The fifth pair of forming rolls 31 and 32 is adapted to further turn the edges of the work -nwardly. The roll 31 has a chan-' sides and is of neled periphery with curved such depth that the edgesof' the work project The roller Y periphery providing a pe ripheral .rib 33 which is adapted to engage the work between its flanges, holding it against the bottom of the channel 'of' the I roller 31, and shouldersfi which engage the edges of the work turning .them inwardly,

as shown Fig. IX. The sets of rollers shaped-to correspond to the rollers 31 and 32 and serve to support the work as it passes from the set of rollers 31 and 32' and also with peripheral flanges 21 The roll 2 i has a correspond 25 and that the angle is more s5 and 3e and 37 are to engage the flanges so that they do not spring or open up.

Between the sets of rollers we, rovide work'supports 38 supported'lby theb ocks 39 so that the supports are in substantially the plane of the peripheries of the bottom rolls. This prevents the work bulging between the rollers and guides the work from one pair to the other.

Our improved pacity and the work produced is very uniform. The structure requires little attention in use and may be-fed or operated "by an unskilled workman. j

We have illustrated and described our improvements as vwe'have embodied or adapted the same for the forming'of curtain rods.-

- VVehalve not attempted to illustrate or, describe other modifications or we believe the disclosure made will enable those skilled in the art to which our inven tion relates to embody or adapt the same as may be desired.

Having thus described our invention, what we claim 'as'new and desire to secure by Let-.
